How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a low-cost way to keep a whole fleet of Plantronics-style office headsets hygienic and comfortable, choose QPOIBSD 20Pcs; if you need to bring a pair of Sony WH-XB700 wireless headphones back to life with proper protein-leather memory-foam cups, choose Xinyuekj WH XB700. For mobile gaming specifically, this is really a question of what you already own — one product is a bulk pack of universal foam covers, the other is a model-specific rebuild kit.
• QPOIBSD 20Pcs — biggest strength: you get 20 foam cushions in one go, sized at 55mm (2.2"), which makes them a practical hygiene and comfort consumable for shared or heavily used headsets.
• QPOIBSD 20Pcs — biggest trade-off: they are generic foam, not a fitted replacement pad, so they suit standard-size earbuds, headphones, walkie-talkies and headsets rather than one exact model.
• Xinyuekj WH XB700 — biggest strength: purpose-built for the Sony WH-XB700, with protein PU leather over memory foam and a stated same-size-as-original fit.
• Xinyuekj WH XB700 — biggest trade-off: it only fits that one headphone family — if your model isn't a WH-XB700, it's the wrong product.
• Who QPOIBSD 20Pcs is for: anyone refreshing multiple headsets, or dealing with worn, unhygienic foam on Plantronics H251/H261/H351/H361-style office headsets.
• Who Xinyuekj WH XB700 is for: a Sony WH-XB700 owner whose original ear pads have flattened, cracked or started flaking.
This is a consumables pack, and that's the whole point. You're getting 20 black foam cushions at 55mm / 2.2" across, made from a high-elasticity, lightweight foam that the spec sheet describes as soft, breathable and skin-friendly. The listing names them for Plantronics H251, H251N, H261, H261N, H351, H351N, H361 and H361N series headsets, and the fit is described as a standard-size office telephone headset fit. The manufacturer also states the foam is compatible with earbuds, headphones and walkie-talkies.
What it does best is solve a small, annoying, recurring problem. Foam ear cushions on office and call-center headsets go shiny, then grimy, then slightly crusty, long before the headset itself dies. The listing makes that exact argument: you replace the unhygienic or worn pad instead of buying a new headset. In practice that means a drawer of spares, a quick swap when a pad gets gross, and a headset that keeps feeling new.
Who should skip it: anyone with a Sony WH-XB700, or anyone who wants a precision-molded replacement pad with a leather surface. This is generic foam, not a tailored cup. If you want an exact cosmetic and tactile match to a specific headphone, look elsewhere. Also skip it if your earcups aren't in that standard-size range — the 55mm figure is the number that matters, and the listing itself says to confirm fit.
One more thing worth saying plainly: this is a hygiene and comfort purchase, not a sound upgrade. You should expect the foam to change how a headset feels and seals, and the listing frames it as reducing noise and improving fidelity — but it isn't a driver, a codec or a tuning change. Check the current price on Amazon before you commit, because the value case here is entirely about how many replacements you actually need.
Xinyuekj WH XB700: Who It's For
This is the opposite kind of product: one specific fix for one specific headphone. The Xinyuekj WH XB700 replacement ear pads are made for the Sony WH-XB700 wireless earphones, and the listing is blunt about it — confirm your headphone model before buying. If you own that set of Extra Bass Bluetooth on-ear headphones, this is aimed squarely at you. If you don't, stop here.
The materials are the interesting part. Protein PU leather over memory foam, with an ergonomic shape the listing says balances quietness, comfort, softness and sound insulation. The product details list the enclosure material as faux leather and memory foam, and the color as blue. That matters if you're trying to match the original look — and the listing claims a perfect fit at the same size as the original, so the headphones should look refreshed rather than repaired.
Installation is described as simple: peel off the old WH-XB700 ear muffs and fit the new ones in minutes. No tools, no soldering, no drama. For a headphone whose pads have gone flaky, that's the whole appeal — you keep the headphone you already like and replace the part that wore out.
Who should buy it: Sony WH-XB700 owners with flattened, cracked or peeling pads who want the soft touch and the sound isolation back. Also anyone who wants a leather-feel surface rather than bare foam, which is a real comfort difference over a long session. The listing describes the cushioning as soft, breathable and suitable for long-term wear.
Who should skip it: anyone whose headphones aren't a WH-XB700. The compatibility is narrow by design, and that's not a flaw — it's the trade-off you accept for a fitted pad. Skip it too if you'd rather spend less on a generic foam cover and don't care about the leather surface or the exact fit.
For mobile gaming on a WH-XB700, the practical argument is sealing and comfort. Better insulation and a proper fit mean the pads sit against your ears the way the originals did, which is what keeps a long gaming session bearable. It won't change the tuning, but it will restore the physical experience the headphone was designed around. Note the listing mentions a 90-day warranty period and an offer to contact them for replacement or refund if something's wrong — worth knowing before you order.
• Best for a Sony WH-XB700 → Xinyuekj WH XB700. It's the only one of the two built for that headphone.
• Best for multiple headsets or shared desks → QPOIBSD 20Pcs. Twenty cushions means you stop rationing replacements.
• Best for leather-feel comfort and sound insulation → Xinyuekj WH XB700. Protein PU leather and memory foam versus plain foam.
• Best for broad compatibility → QPOIBSD 20Pcs. Standard-size earbuds, headphones, walkie-talkies and headsets, per the listing.
• Best for exact-fit cosmetics → Xinyuekj WH XB700. Stated to match the original size and refresh the look.
• Best for simple hygiene swaps on office headsets → QPOIBSD 20Pcs. Plantronics H251/H261/H351/H361 series are named directly.
• Best for a single, quick repair → Xinyuekj WH XB700. Remove the old muffs, fit the new ones in minutes.
• Best for mobile gaming on a budget headset → QPOIBSD 20Pcs. Cheap foam covers keep an inexpensive gaming headset comfortable for long sessions.
In my opinion, the honest answer is that these two barely compete — they solve different problems, and the right pick depends entirely on what's on your head. If I owned a Sony WH-XB700, I'd buy the Xinyuekj set without much hesitation: fitted protein-leather memory-foam cups, a stated original-size fit, minutes to install, and a 90-day warranty period. If I were keeping several headsets alive — an office desk, a shared setup, a budget mobile gaming headset that takes standard foam — I'd buy the QPOIBSD 20Pcs and treat it as a consumables box. For mobile gaming specifically, I'd pick based on the headphone, not the pad: WH-XB700 owner, go Xinyuekj; anything standard-size, go QPOIBSD. Check the current price on Amazon for whichever fits, and confirm your model before ordering — that single check decides this for you.
The Xinyuekj WH XB700. It's designed specifically for that headphone, and the listing asks you to confirm your model before purchase. The QPOIBSD 20Pcs is a standard-size foam cushion, not a fitted WH-XB700 pad.
They're 55mm / 2.2" foam cushions described as suitable for earbuds, headphones, walkie-talkies and headsets. If your gaming headset uses that standard size, they'll work as a comfort and hygiene refresh. If it uses proprietary pads, they won't.
QPOIBSD gives you 20 cushions in one pack — that's the value case. Xinyuekj supplies a replacement pad set for one pair of WH-XB700 headphones. Buy the first for volume, the second for a specific fix.
Neither is a driver or tuning upgrade. QPOIBSD states the foam reduces noise and improves music fidelity, and Xinyuekj states the pads are designed to optimize sound performance with better insulation. Think of both as restoring or improving the seal and comfort, not remastering your audio.
